Positive Grid, the developers of JamUp Pro XT for iOS, has announced a major update to its rockin’ Guitar/Bass iPad and iPhone Amp-Effect Processor.

JamUp Pro XT 2.4 features the 12 Metal Signature Model Pack—a collaboration with three metal masters: guitarists Jeff Loomis (Nevermore), Ola Englund (Six Feet Under, Feared) and Keith Merrow—all are certified and carefully developed by both the artists and Positive Grid exclusively for JamUp Pro XT 2.4. Now you can rock Jeff, Ola and Keith’s six signature amp models and six signature guitar pedals—from ultra clean to trash metal; delay, chorus, four-band parametric EQ to distortion and overdrive—right in JamUp! Also included is a collection of their guitar tone preset settings, provided as starting points for your own tone-tweaking or playing along.

“I’m really excited about the signature amp models they’ve made for me,” Merrow boasts. “When I travel, I always bring my guitar and my iPad loaded with JamUp. You never know when inspiration may strike! They sound crushing! With their addition, the JamUp app just keeps getting better and better!”

“The addition of the Ola ‘War & Peace’ amps on the new JamUp Pro XT 2.4 are closest to the real deal and definitely the only amp sounds you’ll ever need!” adds Englund. “With complete control over the style of gain on the ‘War’ amp, you have the most versatile amp sounds out there, and the ‘Peace’ amp is what I would define as the cleanest of the clean amps. Together, these are a deadly combo on the battlefield!”

“The array of amps and pedal sounds that I use both live and in the studio now available in this app will definitely suit the metal musician or any guitar player who is looking for a quick guitar sound to dial in, be it on the road or in the studio,” says Loomis. “The tones are killer!”

In addition to the signature pack offerings, JamUp 2.4 also packs a host of extra onboard bells & whistles, adding new tackle to your mobile toolbox. Plus, the new update now offers the world’s the first and only in-app ToneSharing platform, allowing you to explore, share and download over 5,000 artists and users presets with our growing JamUp community.
